Exam 3: Measures of Morbidity and Mortality Used in Epidemiology

Blood pressure measurements on adult males 30-39 years of age were obtained in a survey of a representative sample of Twin Cities households. To compare the frequency of hypertension in the white and nonwhite populations surveyed, the most appropriate measure is the:

For a chronic disease of low incidence and long duration, prevalence of the disease increases relative to incidence.

Which of the following terms is expressed as a proportion (as distinguished from a ratio)?

Calculation of the standardized mortality ratio is an example of the direct method of age adjustment.

The risk of acquiring a given disease during a time period is best determined by:

An epidemiologic survey of roller-skating injuries in Metroville, a city with a population of 100,000 (during the midpoint of the year), produced the following data for a particular year: Number of skaters in Metroville during any given month: 12,000 Roller-skating injuries in Metroville: 600 Total number of residents injured from roller-skating: 1800 Total number of deaths from roller-skating: 90 Total number of deaths from all causes: 900 The cause-specific mortality rate from roller-skating was:

Expressing the burden or extent of some condition or attribute in a population:

A prerequisite for using the direct method of age adjustment is that the age-specific death rates in the study population must be stable.

Beach City has a rising population of 500,000 robust, fertile males and 450,000 robust, fertile females. If there were 4000 live births, 3 fetal deaths, and 40 maternal deaths, what is the crude birth rate?
